CHARLES, D. wrrrrn, or Noitwronc, 'ooivnnc'rfcu r,

, estuarine-RING.

To'dZZ may) concern: Be'it'know'n that I, CrrARLns DYLWHITE, a citizen of theUnited States of America, re-

sidingfat Norwich, in the county of New. London, and State' of Connecticut, have invented certain 'new and useful Improve ments in Spinning-Rings, of which the fol-' lowing is a full, clear, andexact description.

This invention relates to spinning rings, and among its objects is the provision .ofv a ring which will produce smoother running of thetraveler, will cause less bowingof the;

yarn,'will save space between the center's of spindles, will enable a lighter traveler to be used for a given size of ring than heretofore, and will cause a faster running of. the spindle as compared with spinning rings of prior known forms.

' I With these and other important obj ects'iii view, the invention comprises a 7 ring which is arranged at a suitable angle, preferably about to a verticalzplane, and'a base portion which lies ina' horizontal plane. By combining the angularly disposed ring with a horizontal base plate, I have found in practice that a traveler of the standard form may be employed, and that the pull of the yarn upon the traveler and the centrifugal force will cause the traveler at its ends to. bear with substantially equal force upon opposite sides of the base plate. This results in equally dividing the frictional engagement between two points, and the resistance to movement of the traveler is not only thereby reduced. as compared with prior rings, but the life of the ring is prolonged. because the wear is not concentrated along a single line. 7

In addition have found that with a ring so constructed a much lighter traveler can be used than where the ring is horizontally disposed or an inclined or vertical base or support is employed. By using a light traveler economies of production, and increased speed of travel,

7 are secured.

. 1% its'preferred form the spinningtringcomprises a b'ase portion 2, an inwardly and downwardly inclined flangeh which is bent t and doubled upon itself, to form the upf .wardly inclined, "conical spinning"ring proper 6, whose "upper free edge projects a substantial distance, above the plane. of the portions of the blank which are doubled upon themselves, that; is, the i downwardly extending fianget and the adjacent part of the upturned ring 6.. Thebase, herein shown I j Specificationpf Letters Patent. PatentQdAuigzSfl,

in the form of aplate 2 occupies a horizontal 1 position, being supported upon thering rail 3 to WillChit may besec'ured'. by any suit ablemeans, as'for, e'xample,"'by screws 8,

which pass through slots 9.'j-' A traveler'10 embraces the upwardly",extending free edge 5 of the spinning ring, and is curved inwardly, and downwardly, and then upwardly to embrace the bent over edge 7, the construction of thering being such that a traveler of the ordinary commercial form' may be used. It will be seen that the-ring, when thus formed from a single piece of sheet metal. may be very economically proe duced by the .use of suitable dies, and by reason of the fact thatthe base portion 2. extends horizontally, and is bent downwardly and inwardly,-and then upwardly to form'the ring, the latter is strengthened and stiffened by the doubled portions of the metal, at 4, 6. J

With an inclined track such as presented by this ring, the path of the traveler is always maintained concentric with the ring,

as the pull upon the thread and the centrifugal force will cause the traveler to slide along the ring and to bear atitsends with substantially equal force, at the points a, b, on opposite sides of the base.

By reason of the angular the ring 6, and the horizontal relation of the base plate, the traveler, whose ends, bear with comparatively light pressure against opposite sides of the plate, will move with less frictional resistancethan in priorcon disposition :of

structions, and hence with higher speed.

There will also be lesswear on the ring than where the traveler is caused to bear hard" against the 'ring'at a single point, and hence the life of the ring will 'belonger than in constructions: Where such condition exists) In addition to 'theseyadvantages, a ring "when constructed in the manner abovedescribedwill produce smoother running "of 'the traveler, will cause less bow in the yarn,-

tice I prefer to produce it of this material,

it will be obvious that some; of the benefits of the invention maybe. obtained by form-' other forms of 'inaterial.

What I claim is :-l i V 513A spinning ring. having base lying in a substantially horizontal. plane, and a raceway disposed .an'gularly thereto, and flared' from'its lower edge outwardly to ward its upper edge, said edges projecting plate metal, or from above and beloWI the plane of the base.
